Geopolymer cement and Geopolymer Concrete

Geopolymer cement is often mixed up with alkali-activated slag developed since 1956 in Eastern Europe by G.V. Glukhovsky. Alkali-activation, which is generally performed with corrosive chemicals (see below User-friendly), is used for the making of concretes exclusively. The alkali-activated materials are not manufactured separately and not sold to third parties as commercial cements. On the opposite, geopolymer technology was from the start aimed at manufacturing binders and cements for various types of applications.

Fly ash is a byproduct from burning pulverized coal in electric power generating plants.

Fly ash is a byproduct from burning pulverized coal in electric power generating plants. During combustion, mineral impurities in the coal (clay, feldspar, quartz, and shale) fuse in suspension and float out of the combustion chamber with the exhaust gases. As the fused material rises, it cools and solidifies into spherical glassy particles called fly ash. Fly ash is collected from the exhaust gases by electrostatic precipitators or bag filters. The fine powder does resemble portland cement but it is chemically different. Fly ash chemically reacts with the byproduct calcium hydroxide released by the chemical reaction between cement and water to form additional cementitious products that improve many desirable properties of concrete. All fly ashes exhibit cementitious properties to varying degrees depending on the chemical and physical properties of both the fly ash and cement.

Our new mixer has arrived!

Global Housing Concepts is rolling out a product line of Basalt Rebar and Geopolymer products in the first quarter of 2014.

Due to the upcoming high demand and the current total lack of availability of these particular specialty products, GHC is buying and shipping both the basalt rebar and the different geopolymer components in the US not only for the company use, but will be the premier outlet providing retail / commercial sales to the general public at reasonable prices. This will enable anyone that wants access to the materials to create their own buildings using sustainable materials. The arrival is estimated for March 2014 and per orders are being accepted.
